DIE-PRESS.

SPECIFICATION formingpart of Letters Patent No. 285,294, dated September 18, 1883.

Application filed February 19, 1883. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE E. MEEKER, acitizen of the United States of America, residing at Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Die-Presses, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention pertains to an improvement in adjusting mechanism for punches, having for its object to compensate wear of the punch; and it consists in the combination and arrangement of parts, substantially as hereinafter more fully set forth.

In the accompanying drawings, Figure 1 is a side view of my improvement with a portion thereof removed. Fig. 2 is a vertical sectional view, showing the adjusting mechanism. Fig. 3 is a transverse section on the line X X, and Fig. 4 is a detail View.

In carrying out my invention I employ, in connection with the head-block A, to which the crank-arm a of the punch-operating machinery is connected, a slide or frame, A, fitted to slide upon the head-block A, said frame a or slide having vertical ribs or ways I) on its inside, which move in grooves b in the sides ofthehead-block. Thehead-blockAisformed in two vertical sections, which are recessed for reception of the crank-arm a and collar or'nut D, and have therein provided (see Fig. 4) an opening, through which projects the nut or wheel 0, and these blocks are rigidly secured together by means of screws projected transversely through the screw-orifices S.

B is a screw with its lower end passed through and shouldered below a plate, 0, fastened to the base of the frame or slide A, to allow it to turn, but not to have vertical movement. The screw B is formed with a radially apertured or socketed nut or wheel, 0, and by inserting a lever or rod into any one of which apertures or sockets of said nut the screw can adapted to work in a screw-threaded collar or nut, D, one section or half of which is held in one half of the head-block, and the other half thereof in the other half of the head-block. It will therefore be observed that by turning the screw in the required direction the headblock A will be caused to move upward, which movement increases the distance between the top of the crankarm a, attached to the operating machinery, and the bottom of the punch, secured to the frame or slide A, this movement being made to compensate the wear of the punch. The crank operating the frame or slide A is attached to the crank-arm a, and to the bottom of the frame or slide A is secured the die-punch, as usual.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

l. The frame or slide A, having ribs or Waysv b, in combination with head-block A, composed of sections E and F, and having grooves I), and Crank a, carrying slide A, screw B, having collar or nut D, and nut or wheel 0, substantially as shown, and for the purpose described.

2. The frame or slide A, having ribs or ways b, in combination with head-block A, composed of sections E and F, rigidly secured together by transverse screws, rabbeted for reception in part of the adjusting mechanism, and grooved to clamp the ways or ribs 6, and suitable mechanism for adjusting head-block A, substantially as shown and described.

In testimony-whereof I affix my signature in presence of two witnesses.
